Answer 1

Answer;

$16,404.2\text{ ft}$

Explanation;

Here, we want to get the approximate number of feet in 5 kilometers

We start by saying there are 1000 meters in a kilometre

So, the number of meters in 5 kilometers will be;

$5\times1000\text{ = 5,0000 m}$

Now, we proceed.

We know that there are 100 cm in 1 meter

Thus, the number of cm in 5,000 m will be;

$100\text{ }\times\text{ 5,000 = 500,000 cm}$

Furthermore, from the question, we have that 2.54 cm makes 1 inch

So, the number of inches in 500,000 cm will be;

$\frac{500,000}{2.54}\text{ inches}$

Finally, we know we want our answer in feet

Mathematically, 12 inches makes 1 foot

Now the number of ft will be;

$\frac{500,000}{2.54\times12}\text{ =16,404.2 ft}$
